Assembly
Installing the bottom bracket
Do not use the Clavicula Road in combination with an E-TYPE front derailleur!
The THM socket wrench(1)(fig. 3), which can be used as a torque wrench, can be ob-
tained from us or from your specialised dealer.
Measure the width of the bottom bracket housing of
your bicycle frame.
Identify the type of front derailleur used on your
bicycle.
Use the table to determine the correct number of
spacers for both sides of the bottom bracket –
see Spacers, page 13.
Make sure that the securing bolt of the derailleur
cable guide does not protrude into the bottom
bracket housing by more than 1mm.
Apply grease to the threads and contact surfaces of
the bearing cups.
BSA/ITA
Fit the correct number of spacers to the right-hand
bearing cup (R).
Screw the right-hand bearing cup (R) – initially by
hand – into the right-hand side of the bottom bracket
housing using an anti-clockwise (BSA) or clockwise
(ITA) motion.
Fit the correct number of spacers to the left-hand
bearing cup (L) (marked by groove).
Screw the left-hand bearing cup (L) – initially by
hand – into the left-hand side of the bottom bracket
housing using a clockwise motion (BSA & ITA).
(fig. 2)
Tighten both bearing cups using a tightening torque
of 40N·m (354lbf·in).
This torque corresponds to a manual force of
approx. 20kg (44lb) at the end of the THM bottom
bracket tool.
